In my personal opinion though, as a Imperial lover I can understand why people find they boring, they do seem rather full of it and they seem like an establishment which needs to be brought down. The thing is, thats actually why I seem to like them, because they are just like me, as in arrogant, pompous, can conquer a continent by charm and diplomacy, genius basically.
Orcs, I can also understand why people don't like them, they must remind everyone of the bully of the schoolyard back in primary school, big and ugly, with the IQ of a peanut.
